We have several service desk projects with many external users each.
Our goal is to have anyone be able to access a specific project portal link, create an account (if needed), submit a ticket, but then only be able to see the issues for the project they submitted for.
This seems like it should be straightforward, but I am finding the only ways to limit external users to one project is to restrict access to each project, then manually add the users we want to each project. There are too many external users flowing in and out for us to manage that.
